Pericentric inversion diseases
WebBackground: One of the frequent occurrences in chromosome rearrangements is pericentric inversion of the Chromosome 9; inv (9) (p11q12), which is consider to be the variant of normal karyotype. Although it seems not to correlate with abnormal phenotypes, there have been many controversial reports indicating that it may lead to abnormal clinical conditions … WebPericentric inversions are more common than paracentric inversions and occur when the breaks are on opposite arms or sides of the centromere ( Fig. 5.3A ).
